The UK scientists who developed a prototype chocolate printer last year say they have now perfected it. They hope to have the machine on sale at the end of April. It would allow chocolate lovers to print their own custom-made sweets, layer by layer. Lead scientist Dr Liang Hao, from the University of Exeter, founded the Choc Edge company to commercialise the device after interest from retailers. 3D printing using plastic, wood and metal is already widely used by industry to create objects ranging from jewellery and footwear to human bones. Dr Hao told the BBC that chocolate printing, just like any other 3D printing technique, starts with a flat cross-section image – similar to that produced by ordinary printers turning out images, and then prints out chocolate layer by layer to create a 3D shape, without any moulding tools.
